Improvement in lubricators



DAVID ADaMsoN, or NEW Youri,

Leners Patent No. 97,470,

dated December 7, 1869.

Move- IMPRovI-:MENT IN LUBRICATORS.

The Schedule `referred to inV these Letters Patent and making part of the same.

To all whom 'it may concern:

Be itknown that I, DAVID ADAMsoN, of the city, county, and State of New York, have invented a new and improved Lubricator; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specitication.

The drawing represents a side view, partly in seetion, of my improved lubrcator.

This invention hasfor its object to provide a lubricator-cup, which can be used on all'kinds of machinery, but more particularly on high-pressure engines, with any suitable Viscid lubricating-material.

The invent-ion consists in the arrangement of acylindrical cup, which containsa piston, to the yupper or outer surface of `which steam-pressure'is or can be applied.

The advantages of this cup are, first, that it can he applied in a horizontal, as well as in a vertical positiou; that it can be used with viscid or coagnlating lubricating-material; and that by' regulating the steampressnre, the ow of lubricati11g-material can also be easily regulated.

A,iu the drawing, .represents the lubricating-cup.

'It is of .cylindrical form, and is supported by its hollow shank c, which is secured inthe requisite p0- sition to the machinery.

lutoV the cup A is placed a close-t-ting piston, B,

which is inserted when the screw-cap or cover` C of cup A is removed, .and subsequent to the insertion ofl the lubricating-material.

The stem b of .the piston may be made to project through the cap C, in which case steam-tight packing is applied to the same.

D is the steam-pipe, entering the upper-:part ofthe cup A, between the cover and the piston of the same.v The steam carried by the same into the cup will force the lubricating-material into the stem, and .thence to the desiredposition.

The flow of steam is regulated by a cock, c, in the pipe D, and that of the lubricating-material by another cock, d, in the shank a..

The lubricating-material may be of petroleum residue or other viscid or coagulating-material. The latter kind can only be made liquid by heat, and the outer pressure for forcing it out ot' the cup will aid considerably in itsapplication. Y

- Having thus described my invention,

= I claim as new,'and desire. to secure by Letters Patent-.-

A lubricator-cup, containing a piston, and connected with a steam-supply pipe, through which steam can vbe brought to bear upon said piston, as set forth.

DAVID ADWAMSON.
